Summer is a time for travel, and whether you’re simply heading across the country to visit family or making the trek across the pond for the once in a lifetime chance to see the London Olympics, you’ll want to download this packing app.

Packing Pro will help you organize everything that you need for any trip, so whether you’ll be gone just for the weekend or for more than a month, you won’t forget any of the essentials with this app.

When the app opens you can create a new list or view a sample list, which allows you to see everything that the app is capable of doing. When you go to create a new list, you can use the sample list as a base, use a previous list, or start a new list from scratch.

First you’ll need to enter a name for your packing list and your departure date. Then you can add categories, which helps you to keep everything that you will need to do organized.

For example, there’s are categories for clothing, essentials, toiletries, and gadgets, but there are also categories for babies, pets, and kids, in case you’re packing for more than one person.

In addition to the premade categories, you can also create your own. I added in “Plants” to remind me to make a guide on how and when to water my garden when I’m gone this August.

The first step is to enter all of your to-do information, which contains the things you need to do before you leave, then you can move on to adding the things that you need to pack.

To help you even more, there are categories within each category, reminding you to pack essentials like socks and underwear. Simply tap a category, then add the number of items you need. I’ll be gone for ten days, so I need at least ten pairs of socks with me.

And if you thought that was the end of the categorizations, it’s not. When selecting the socks that you need to add, you can choose from long, short, dress, hiking, sports, and more, or add your own categories. This is a very specific app, which makes packing a breeze.

You really only need to set up a detailed list once, and from there, you can use it for all of your other trips. After all, we often take the same things along with us, including electronics, clothes, and other essentials.

This app has categories and entries for almost everything you would ever need to pack or do before or during a trip. You can even set a reminder to update your Facebook page and kill the mosquitos in your hotel room.

As you pack, you can check things off, ensuring that you will never forget something important. I often forget to pack something essential, like pajamas, or a cell phone charger, which won’t happen again with this handy app.

What I liked: This app is an all inclusive packing planner that will help you organize before, during, and after the trip. You can even keep using it when you get home with reminders to do the laundy and catch up on work email.

What I didn’t like: It’s really in-depth, which means it can take quite some time to set up, when packing takes just an hour or two. It may be more packing help than some people require, but if you put in the work, you definitely won’t leave anything behind.

To buy or not to buy: If you travel a lot, or if you’re planning a major trip, I would definitely suggest spending the $2.99 on this app. It’s an inexpensive way to get peace of mind, making sure everything’s been taken care of.
